          Everything that is put in the a clustered web session needs to be serializable (otherwise it can't be sent to the other servers in the cluster)

           

          It seems like Spring are trying to save "WebAppClassLoader" in the session!

            Hi Anders, Thankyou for your response. Can you tell me how to serialize webappclassloader and is it possible to make it serializable. Thanks!!!

              As it is a JBoss class you will have to change the code and recompile the application server. But I do not think that it will be the correct way. Can't see why you would like to put a classloader in the session. I believe this is a Spring question and I do not no anything about it, sorry!
